The one week countdown has begun for the closure of the L-4 Salmon Creek Bridge on Littlerock Road SW. Crews have already begun prep work and staging, and on Monday, August 11 the crossing will close for up to eight weeks while crews install a new bridge structure.
"We know having the bridge closed is a real inconvenience for residents and area businesses, but we've worked with the contractor on a plan to keep the closure period to a minimum and get the bridge re-opened to traffic as soon as possible," said Interim County Engineer Scott Lindblom. "We're asking drivers in that area to help keep everyone safe and keep this project on track by slowing down and using caution in the construction zone."
Crews have been hard at work since July 14 prepping the old bridge for demolition and staging the equipment and materials needed to construct a brand new bridge. On Monday, August 11, the crossing will close and the temporary Bailey bridge will be dismantled to make way for the new bridge structure. All motorists will need to use the detour route once the bridge closes August 11.
County commissioners approved a temporary road closure that gives contractor Active Construction, Inc. up to eight weeks to complete the first phase of the project before re-opening the bridge crossing. This temporary closure will allow the contractor to accomplish more work in a shorter time to expedite the re-opening of the bridge.
Once the new bridge structure re-opens to traffic, crews will continue working on the bridge, and motorists using the bridge are asked to drive slowly and take caution in the active construction zone to help keep workers safe. The new bridge is expected to be complete by the end of the year.
The L-4 Salmon Creek Bridge on Littlerock Road SW located between 110th Avenue SW and 93rd Avenue SW was first closed on Monday, January 27 after structural deficiencies were discovered. In March, a modular temporary bridge structure called a Bailey bridge was installed at the L-4 Bridge crossing on Littlerock Road SW. With the help of crews from the Washington State Department of Transportation, the Bailey bridge opened Saturday, March 22 and has allowed passenger vehicles, buses and emergency vehicles to travel northbound and southbound using a single alternating lane.
